Educators who have said, "We don't like that, so we'll continue to teach as if it's not happening," are just aggravating the gap between what happens in schools and what happens in the real world. Because of their personalities, or for cultural reasons, some kids might better express themselves through moving images and sound.

I don't like MTV, and I don't like the culture that goes with it. It's OK in very small doses, maybe. Nevertheless, it's a social reality and has influenced how kids perceive things around them, the pace of life and the way people do things.

I prefer software where kids build something and run into problems they have to solve.

Until very recently, most knowledge was inaccessible to people who couldn't read text. But this is changing. The computer opens up other channels of gaining knowledge. If someone is blind, we now have very good machines that will read to him. If someone can't recognize letters, he also will have access to knowledge through sound and images.

My ex-student, Idit Harel, who wrote a book, "Children Designs," has a documented story of a kid who was very shy, isolated and didn't talk much to other kids. She was a little overweight, and the other kids looked down on her for that reason.But then she made a discovery about how to do something on the computer. The discovery was picked up by other kids, and within a few weeks there was a total transformation. This kid was now in demand. And that changed her feeling about herself.

The goal is to teach in such a way as to produce the most learning from the least teaching.

The role of the teacher is to create the conditions for invention rather than provide ready-made knowledge.
